Title: Drop prevention apparatus using magnetic force in scribe head for dividing substrate
Inventor: JEONG SEONG HOON
IPC: C03B33/033
Filed: 2019-08-30
Abstract: The present invention relates to a fall prevention device for a substrate parting scribe head using magnetics.The fall prevention device for a substrate parting scribe head using magnetics comprises: a housing; a drive part mounted in the housing; an elevation unit which receives power transmitted from the drive part to move up and down; and a magnetic levitation part which applies upward magnetic levitation force to the elevation unit to prevent the elevation unit from falling when the drive part cannot operate. Accordingly, the fall prevention device for a substrate parting scribe head using magnetics is configured to provide elevation return force which is always equal in magnification by using the principle of magnetic levitation, so reliability is correspondingly good, the operation is superior in precision and can be greatly increased in efficiency, and no noise etc., is generated. Moreover, there is no variation in output in spite of long-period use, and there is no problem caused in terms of hysteresis to provide semi-permanent use. In addition, since a plane including a guide part for guiding the elevation of the elevation unit passes through a central axis of a ball screw, an eccentric force is not applied to the ball screw, so that precise control of a parting wheel is possible.
